  I built two tools designed specifically for traders — the Position Size Calculator and the Compounding Profit Calculator. The first helps traders determine their optimal position size based on risk tolerance, while the second visualizes account growth through realistic compounding projections, daily returns, and withdrawals. Both tools were created completely no-code, using only smart formulas and logic — proving that powerful, useful tools can be built without writing a single line of code.
